McConnell questioned whether Obama is taking the threat from the Islamic State in Iraq and Syria (ISIS) seriously enough and demanded he immediately present to Congress a strategy for neutralizing ISIS.

“The president should come up with a strategy, present it to Congress, address the American people and tell us how he believes we should stop them,” McConnell said on the Fox Business Network. “This is not in my view a manageable situation. They want to kill us.”

McConnell said ISIS probably poses a greater national security threat than al Qaeda did in the aftermath of the 9/11 attacks.

“This is a serious threat to the United States, to our national security. And the president is the guy who needs to lay before Congress and the American people a strategy to deal with it,” he said.

But Senate Democrats facing tough reelection races this fall are not eager to vote on a measure authorizing renewed military involvement in Iraq. They worry it could demoralize liberal voters who worry that military strikes would lead to another protracted U.S. deployment in the Middle East.

McConnell called Obama the “CEO of our country” and the “commander in chief” and claimed some Democrats such as Sen. Bill Nelson (D-Fla.) are frustrated they haven’t seen a plan of action from the president.

The president drew fire from other conservative critics Wednesday after he proposed during a public appearance in Estonia that the international community could mobilize to contain ISIS.

“We know that if we are joined by the international community, we can continue to shrink ISIL’s sphere of influence, its effectiveness, its military capability to the point where it is a manageable problem,” Obama said, using an alternative acronym for the militant group.
